"And, importantly, we continue to achieve revenue growth while maintaining effective control over operating expenses," added Duperreault. "As a result, we produced 10% growth in adjusted EPS [earnings per share] for the quarter -- a solid start to the year."

Consolidated revenue in the 2011 first quarter was $2.9 billion.

Marsh & McLennan Cos. reported a slight jump in compensation and benefits expense for the quarter, to $1.7 billion, from about $1.6 billion last year.
Duperreault said the positive momentum at the company continues with good underlying revenue growth fueled by new business development and high client revenue retention rates.
Marsh & McLennan Cos. recently underwent several management changes. In April, it announced the appointment of Daniel S. Glaser to the newly created position of group president and chief operating officer. Glaser was chairman and chief executive officer of Marsh, a position he assumed in December 2007.

Duperreault said during the call that Marsh & McLennan Cos.' strategy "focuses on the characteristics that create exceptional value and superior returns for investors: long-term growth, low capital requirements, side-cash generation with disciplined capital management, and a low risk profile.
